For those who prefer tubular over clincher wheels, 4ZA Cirrus Pro T30 TUBULAR was created to be the ultimate all-round tubular wheelset striking a perfect balance between low weight, maximum efficiency and all day comfort. The wide and relatively shallow rims provide extra stability and stiffness where it counts while still keeping an aerodynamic advantage. Whether you head out to climb the highest peaks, participate in an all day century or want to attack the cobbles, 4ZA Cirrus Pro T30 gives you the speed and control to perform your best!
4ZA Carbon Rims
4ZA Cirrus Pro carbon tubular rims are constructed using Aerograde T800 Unidirectional carbon fibers which are bonded with a special resin, capable of handling high temperatures. This guarantees best-in-class performance and reliability. 4ZA T30 tubular rim's profile has been designed to offer maximum stability, low weight and perfect handling, while also taking benefit of the CFD designed 30mm aero shape. 4ZA's proprietary Basalt Infused Composite” (B.I.C.) brake-track area dramatically improves brake performance and decreases heat built-up caused by the brake pads especially on long descents or hot days.
